ATTACHMENT FOR BRUSHES.

1 Application filed May 23, 1914. Serial No. 840,399.

To all whom-it may concern: 1

Be it known that I, LEVI F inns, a citizen of the United States, residing at Evansville, in the county of Vanderburgh and State of Indiana, have invented certain new and useful Improvements in Attachments for Brushes, of which the following is a specilication.

This invention has reference to attachments for brushes and other implements of a like nature, and it proposes briefly, an im proved device which is designed for connection to the handle of the implement, and to which, in turn, the brush head,or its equivalent is detachably and adjustably connected, the arrangement being such that notonly is the purchase of a new handle rendered unnecessary when the brush becomes entirely worn out, but the said head, during its period of use, is also enabled to be adjusted both vertically and angularly, whereby it may be positioned to suit the character of the particular work or to bring an unworn part into play. i

The invention is especially applicable to street-sweeping brushes, but it is obvious that it may be employed with equal facility in connection with various other types of brushes and other implements for sweeping, dusting and cleaning or polishing pavements, sidewalks, floors and other flat surfaces of a like character, which implements are generally pushed forward during their operation.

An embodiment of the invention is illustrated in the accompanying drawing, whereof:

Figure 1 is a plan view of the improved attachment; Fig. 2 is a longitudinal section; and Fig. 3 is a transverse section taken on line 33, Fig. 2.

As shown in said drawing, the attachment, which is constructed of metal and in any desired size, consists, essentially, of asocket member 5, provided at its lower end with a head 6 having a recess or seat 7 therein; a member 8 to which the head of the brush or its equivalent, (not shown), is directly attached, such member being pivotally mounted in the recess or seat 7 and a suitable means 9 coacting with the aforesaid member 8 for retaining the same in adjusted position.

The first of these elements, namely, the

socket member 5, is designed to receive within its bore the lower end of, the handle 10 of,

the implement, and the above-mentioned re- Specification of Letters Patent.

cess or seat 7 in its head 6 is preferably in the nature of a bifurcation which extends vertically therethrough, as shown, the upper portions of the two wings 11 resulting from the formation of the bifurcation being cut away at their front corners so as to produce a pair of forwardly-projecting ears 12.

The attaching member 8 consists of a frusto-conical body 13 which is hollowed to form a similarly-shapcd seat let that opens upwardly through the under face of said body but terminates short of the upper face thereof, thus leaving a wall 15 which serves as the roof of the seat 14 and through which a central opening 16 is formed. The rear portion of the body 13 is provided with a lateral neck 17, which extends into the bifurcation 7 in the head of the socket member and is pivoted therein upon a cross-pin 18, such construction enabling the member 8 to be rocked bodily in either direction about said pin as a fulcrum, in order to raise or lower the body 13. To hold the aforesaid body 13 in adjusted position, the retaining means 9, hereinabove referred to, is utilized,

said means consisting, by preference, of a rocker which is likewise disposed within the bifurcation7 and is pivoted upon a crosspin 19 that passes through its enlarged upper portion. The lower or stem portion of this rocker is reduced in width, and is provided with a forwardly-projecting tooth 20 that is designed for interchangeable engagement with the teeth 21 formed upon the rear end of the neck 17,through the influence of an expansible coil spring 22, the said spring being disposed in a seat 23 formed in the rear wall of the bifurcation and having its front end fitting in a seat 24 formed in the rear face of the rocker stem. The contact point between the springand the rocker stem is obviously located below and to the rear of the pinlf), the forwardlyprojecting upper corner 25 of the rocker thus constituting a fingenpiece which is adapted to be depressed when it is desired to effect the disengagement of the teeth 20 and 21 and the subsequent adjustment of the attaching member.

The attachment of the brush, or its equivalent, to the body 13 of the member 8 ishere shown as accomplished by means of a threaded bolt 26, which isadapted for insertion in a correspondingly threaded opening inthe back of the brush. Said bolt is provided at its upper end with a tapered polygonal head 27, which fits" rotatabl'y in the seat 14:, and adjacent said head with a circumferential flange or collar 28,the=purpose of the said head being to permit, the bolt to be grasped by a wrench in the usual manner and screwed into the opening in the brush back. The bolt head is provided upon its top with an upstanding, threaded pin or stud 29, which is adapted to project through theopening 16 in the roof of the body 13, and which carries a wing-nut 30' that is tightened against the outer face of said roof after the positioning of the brush and the bolt have been com-pletedi- It will be understood, therefore, that the nut 30 may be loosened and the brush then turned to any desired position with respect to the handle, tosuit the character of the work, or to bring an unwornportion into play,' ai ter which said screw will again be tightened, thus drawing the top of head 27 against the under face of roof 15, the screw itself binding against the outer face of said foot. When this adjustment has been" completed, the, rocker may be operated to permit" the vertical adjustment of the member 8 as previously described.

I claim-:

it. An attachment of the character specifled consisting of a socket member adapted to receive a handle end,- and provided at its lower end with a recess, the rear wall of said recess having a seat formed therein; an attaching member provided with a rearwa'rdly projecting neck which is pivoted in said recess for movementin: a vertical plane, the rear end of said neck being formed with averti'cal series of teeth; a retaining member pivoted in said recess and having. a reduced, lower portion provided with a tooth adapted for interchangeable engagement with the first-named teeth, and a spring disposed in said" seat and bearing against said reduced portion, to hold said tooth in such'engagement', said retaining member having a forwardly projecting upper corner constituting a finger-piece which is adapted to be depressed to release said tooth from such engagement.

2; In an attachment of the character specified, the combination, with a socket member adapted tO IBCBIVG a handle end; of a hollow, frusto-conical attaching member connected to said socket member, the top of said attaching, member being provided with a: central opening; a threaded bolt having a substantially frustdconical head rotatably fitted insaid attaching member and provided at its top with a threaded pin extending. throughysaidi opening; and a retaining member carrie'dbyl said: pin and-'engageable with" the: top of: said attaching member.

- 3. I-n' an attachment of the character specified,- the combination-of a socket member adapted toreceiver ahandle: end; a 1101- low, frusto-conical attaching member connected to-thelower end of said socket. memher and having: an: opening formed centrally througlr its; to 'p threadedbolt having a substantially frusto-eoniea-l head rotatably fitted in said attaching, member and provided at its top with a threaded-pin extending through said opening; and a nut carried by said pin and" adapted to be frictionally engaged with the top of said attaching memberto'retain' said bolt head in adjusted position.

lintestimony whereof I affix my signature in presence of: two witnesses;
